CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation-in-part of U.S. application Ser. No.13/102,196 filed May 6, 2011, which claims the benefit of U.S.Provisional Application No. 61/332,217, filed May 7, 2010 and hereinincorporated by reference.

TECHNICAL FIELD

The present invention relates to a holder for personalcomputing/communicating devices and, more particularly, to a portableholder that can be easily mounted on the shelf, providing sufficientsupport for the device, yet is able to be quickly and easily removedfrom the shelf and moved to another location.

BACKGROUND OF THE INVENTION

There are many environments today, such as hospitals, labs, classrooms,offices, homes, or the like, where laptop computers are used and theworkspace designated for these devices may be insufficient, cluttered orotherwise not available.

In today's society, for example, many people utilize their laptopcomputers (hereinafter simply referred to as “laptops”) in a kitchensetting. A chef can perform on-line research for recipes while cooking.A mother can use social networks while performing other kitchen chores.A stock broker can monitor trades, and a business person can check emailwhile having breakfast. Laptops are becoming ubiquitous in medicaloffices or hospitals, where each examining room may include a laptop,the group of laptops then networked together to collect patientinformation in an efficient manner.

A laptop (or notebook, netbook or similar portable computing device) isa very expensive piece of equipment and needs to be protected fromharmful elements in many of these settings; “clutter” on a counter in aresidence (for example, in the kitchen) or medical building (forexample, in a patient examining area) may result in contaminating orotherwise damaging a laptop. People who use laptops in theseenvironments are often “on the move”, and do not sit down and use theirlaptop at a fixed location. Indeed, sitting down to use a laptop may beuncomfortable, and leaning over a laptop may not be ergonomicallycorrect.

U.S. Pat. No. 6,601,609 issued to D. R. Cress et al. on Sep. 16, 2003discloses an apparatus for supporting articles above a “work surface”such as a counter. The Cress et al. apparatus comprises a wire metalbracket that is supported by a pair of braces that are permanentlyattached to the underside of a shelf (or other raised area). The braceshold the wire bracket in a manner such that the bracket can be rotatedout of sight when not in use. This is required inasmuch as the bracketis permanently attached to the shelf. It is not presumed that the wirebracket of Cress et al. could support the weight of a conventionalcomputer laptop. Moreover, the need to permanently attach the braces toa shelf for support is considered to limit the usefulness of the Cresset al. arrangement.

U.S. Pat. No. 7,124,988 issued to L. A. Duffy et al. on Oct. 24, 2006discloses a “portable” device for supporting a load in a cantilevereddisposition relative to a shelf, cabinet or the like. The Duffy et al.structure is a multi-component arrangement including a two-part, hingedbracing structure that reaches underneath a shelf and also extendsoutward therefrom. A separate metal bracket, attached along the hinge,contacts the top surface of the shelf to hold the arrangement in place.The various components are connected along a hinge that allows for themto pivot and “close” onto one another for storage purposes.

A wall-mounted arrangement for supporting a laptop computer in anenvironment such as a medical examination room is disclosed in U.S. Pat.No. 6,246,573 issued to E. Khan et al. on Jun. 12, 2001. While suitablefor use with a laptop, the wall-mount structure of E. Khan et al. cannotbe adapted for use with a shelf in a cabinet and is not portable.

For situations where a user desires to access a relatively smallelectronic computing/communication device (e.g., tablet, cell phone,e-reader, or the like), it may be desirable to be able to change theviewing angle, as well as the orientation of the device itself (i.e.,between horizontal and vertical). Any of the “fixed” attachmentarrangements of the prior art do not—and cannot—accommodate thesedesires.

Thus, a need remains in the art for a portable support system for apersonal computing/communicating device that is simple in form and iscapable of being removably attaching to a shelf in a wall-mountedcabinet or the like.

SUMMARY OF THE INVENTION

The need remaining in the prior art is addressed by the presentinvention, which relates to a holder for laptop computers and, moreparticularly, to a portable holder that can be easily mounted on theshelf, providing sufficient support for a laptop, yet is able to bequickly and easily removed from the shelf and moved to another location.More particularly, the present invention also relates to a holder forpersonal computing and/or communicating devices and, more particularly,to a portable holder that can be easily mounted on the shelf, providingsufficient support for the device, yet is able to be quickly and easilyremoved from the shelf and moved to another location.

In accordance with one embodiment of the present invention, a portablelaptop holder comprises a base support tray upon which the laptop (orany other device) is placed, including a device retaining portion forholding the laptop in place. An upper end termination of the supporttray includes an arrangement for removably attaching the tray to astandard shelf (such as in a wall-mounted cabinet, a bookshelf,tabletop, or the like). The device retaining portion may take the formof a lip (curved end) formed along the lower termination of the supporttray, a non-skid surface material on portions of the tray, strap memberssurrounding the tray, or the like.

In one embodiment, the upper end termination of the tray may comprise anopen C-channel, with one or more mounting screws passing through tofacilitate attachment of the C-channel to the shelf, the mounting screwscoming to rest against the underside of the shelf. In an alternativeembodiment, a pair of corner support brackets are attached to the upperend termination of the support tray and engage with the sidewalls of thecabinet to fixedly hold the tray in place.

The tray itself may be formed of a single piece of material, or aplurality of separate pieces joined together. The tray may include oneor more ribs for additional rigidity and/or ventilation holes. The traymay be fixed in size, or adjustable in both width and length. Variousmaterials (including metals and plastics) may be used to form theportable laptop holder of the present invention.

In another embodiment, the present invention comprises a portable holderfor removable attachment to a shelf, where the portable holder is usedto support a relatively small electronic device (such as, for example, atablet, cell phone, e-reader or the like). The portable holder comprisesa central support member for supporting the electronic device, a deviceretaining element coupled to a lower edge of the central support memberand an upper attachment means coupled to a top edge of the centralsupport member. The upper end termination is used to removably attachthe portable holder to a shelf, and the holder is particularly formed toallow for the viewing angle of the device to be modified, as desired bythe user. In one arrangement, the holder can be rotated while attachedto the shelf, so as to be located in a preferred direction for the user.

These and other attributes and aspects of the present invention willbecome apparent during the course of the following discussion and byreference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

The present invention addresses the above concerns associated with usinga laptop in a space-limited environment, such as a kitchen, medicalexamining room, or the like. In particular, the present invention isrelated to a portable laptop holder that may quickly and easily beattached to a shelf, allowing for the laptop to be positioned at aproper level for a user, yet remain removed from kitchen/medicalappliances, counters, and other areas where damage to the laptop mayoccur.

FIG. 1 is an isometric view of a portable holder 10 formed in accordancewith the present invention. It is an important aspect of the presentinvention that laptop holder 10 be completely portable, capable ofhanging onto virtually any standard-sized cabinet without the use of anyadditional hardware or support elements. That is, there is no need toinstall any other shelving, brackets or support elements on the cabinetsthemselves. Holder 10 may therefore be taken by the user from onelocation to another and easily used with various cabinets, in anylocation or setting. It is to be understood that while most applicationsand the following examples are associated with using the portable holderwith a wall-mounted cabinet, the inventive portable holder may be usedwith a bookshelf, wall-mounted shelf, tabletop, or any other flatsurface.

Referring to FIG. 1, portable holder 10 is shown as fixed in position toa bottom shelf 20 of a wall-mounted cabinet 22. As shown, portableholder 10 comprises a tray portion 12 for supporting a laptop computer(or other electronic/communication device, book, papers, etc.) thatterminates in a device retaining element 14 in the form of a lower lipthat curves upward and functions as a “stop” to hold a laptop computer(or any other device) in place. Portable holder 10 further comprises anupper end termination 16 of tray 12 that engages with shelf 20 to secureportable holder 10 in place. When used with a wall-mounted cabinet, therelatively low profile of portable holder 10 allows for cabinet door 24to be closed with holder 10 still in place.

In accordance with the present invention, upper end termination 16includes attachment means 18 for removably attaching portable holder 10to shelf 20. While various specific configurations may be used in thedesign of attachment means 18, it is important that the attachment besecure enough to fixedly support both holder 10 and a laptop positionedon the holder, yet be easy enough to “loosen” such that holder 10 can bequickly dismounted from the shelf and moved to another location (orstored away).

In the particular embodiment shown in FIG. 1, attachment means 18comprises at least one bolt 19 disposed through a portion of upper endtermination 16. Bolt 19 includes a threaded shaft 30, terminating in ahead 32 for contacting the underside of shelf 20. A wing nut 34 ispositioned along threaded shaft 30 underneath upper end termination 16for controlling the movement of threaded shaft 30 with respect to upperend termination 16 and securing the engagement of head 32 with theunderside of shelf 20. In particular, once upper end termination 16 isin place with respect to shelf 20, wing nut 34 is used to tighten head32 in place against the underside of shelf 20 and prevent holder 10 frommoving with respect to shelf 20. When holder 10 is no longer needed,wing nut 34 is loosened to release head 32 from shelf 20, allowingholder 10 to easily be removed. Using the threaded bolt as an attachmentmeans allows for the thickness of various shelves to be easilyaccommodated. However, it is to be understood that attachment means mayinclude a variety of other arrangements that may be quickly and easilyused to removably secure holder 10 to shelf 20 (including, for example,latches, suction arrangements, or the like).

FIG. 2 is another isometric view of holder 10, showing in this case theuse of a pair of bolts 19-1 and 19-2 disposed at either edge of upperend termination 16. Each bolt 19 is shown as including a threaded shaft30, head 32 and wing nut 34 as described above. Also evident in thisview is the formation of upper end termination 16 as an open C-channel(various other configurations are possible and considered to fall withinthe scope of the present invention). This specific configuration ofupper end termination 16 is defined as including an engaging surface 40that fits over the top of shelf 20 (see FIG. 1) and a pair of lowerfixturing portions 42, 44, disposed at opposing edges of upper endtermination 16. As shown in FIG. 2, a first threaded shaft 30-1 isdisposed through fixturing portion 42 and a second threaded shaft 30-2is disposed through fixturing portion 44. Bolts 19-1 and 19-2 are thentightened in the manner described above to secure holder 10 in placewith respect to shelf 20.

In one embodiment, lower fixturing portions 42, 44 may be formed asrotating members to facilitate the quick removal/installation of holder10 with respect to shelf 20. FIGS. 3 and 4 illustrate the rotatingmovement of lower fixturing portions 42, 44 in a rear view of holder 10.As shown, lower fixturing portions 42, 44 are formed as separate membersthat rotate with respect to tray 12, where portions 42, 44 rotate inwardto swing out of the way of the attachment process. FIG. 3 shows lowerfixturing portion 44, including bolt 19-2, being rotated toward theinterior of holder 10. FIG. 4 shows both lower fixturing portions 42, 44in their fully inwardly rotated positions. In this position, therefore,holder 10 may be easily positioned along shelf 20 (not shown) and oncein position, lower fixturing portions 42, 44 rotated upward to contactthe underside of shelf 20.

Advantageously, tray 12 is angularly disposed with respect to upper endtermination 16 so that when a laptop is positioned on tray 12 it is at a‘user-friendly’ orientation. FIG. 5 is a side view of portable holder 10illustrating the angular displacement θ between upper end termination 16and tray 12. An angle of about 115° has been found useful; however, anyangle in the range of about 100°-130° is considered appropriate for thisuse, the particular angle at the discretion of the designer. FIG. 6 is aside view of portable holder 10 as positioned in place along shelf 20 ofcabinet 22 (with cabinet door 24 being closed and shelf 20 not visiblein this view), showing the support of an exemplary laptop 100, with theangular displacement allowing for a comfortable use of the keyboard 110of laptop 100. FIG. 7 is a front view of portable holder 10 aspositioned within shelf 20 of cabinet 22 and supporting laptop 100 at auseful location, raised above the counter surface. FIG. 8 is anisometric view, with the cover of laptop 100 nearly closed and cabinetdoor 24 open, illustrating the engagement of upper end termination 16with shelf 20 in cabinet 22.

FIGS. 9-13 illustrate various alternative configurations for supporttray 12, device retaining element 14 and upper end termination 16. FIG.9 illustrates tray 12 and device retaining element 14 (in the form of alower lip element 14), where in this case tray 12 has been particularlyconfigured to include a plurality of ribs 121 that are considered to addrigidity to the structure. FIG. 10 shows an embodiment of tray 12include a plurality of vent holes 123 (in this case, in the form ofelongated openings) that may be incorporated with tray 12 to provide aircirculation and provide overheating of a device positioned upon tray 12.

FIG. 11 illustrates an alternative configuration of device retainingelement 14, in this case in the form of a slip-resistant material 141that is disposed over at least a portion of the upper surface of tray12. The material is selected to provide sufficient frictional force tohold a device in place on tray 12. In this case, there is no lower liptermination included along tray 12. FIG. 12 shows yet another type ofdevice retaining element 14, in this case comprising at least one strap143 that is disposed around tray 12, strap 143 having a sufficientdegree of elasticity to secure the device (such as a laptop) in place ontray 12. Again, there is no lower lip termination for this particularembodiment.

FIG. 13 illustrates an alternative configuration of upper endtermination 16, in this case comprising a pair of corner brackets 161,162. Corner brackets are described in detail hereinbelow in associationwith other alternative embodiments of the invention. In each case,corner brackets rely on the availability of a shelf including a verticalsupport (such as a cabinet wall, bracing between adjacent shelves, orthe like), where corner brackets 161, 162 engage the backside of thevertical supports to firmly attach holder 10 to shelf 20.

The embodiment as illustrated in FIGS. 1-13 comprises a portable holder10 where tray 12, device retaining element 14 and upper end termination16 are of (preferably) unitary construction—comprising either a ruggedplastic material or a metal or composite, as appropriate. As mentionedabove, it is also possible to form holder 10 of multiple components and,in this case, further possible to adjust both the width and length ofthe holder itself.

FIG. 14 illustrates an alternative, multi-component embodiment of thepresent invention, shown as an adjustable, portable holder 50. In thisembodiment, the support tray portion comprises a pair of side supportmembers 52, 54 with at least one horizontal support bar 56 disposedtherebetween. This arrangement allows for sufficient air flow around thelaptop and prevents overheating. The specific embodiment of FIG. 14includes a pair of horizontal support bars 56-1 and 56-2. FIG. 15 is afront, plan view of the multi-component embodiment of FIG. 14.

Referring to both FIGS. 14 and 15, the device retaining element ofholder 50 is shown as comprising a pair of upward-curving front stops62, 64, with front stop 62 attached to a lower end of side supportmember 52 and front stop 64 attached to a lower end of side supportmember 54. For configurations where the width of holder 50 isadjustable, it is preferable to form device retaining element asseparate segments so as to facilitate the ability to adjust the width ofholder 50.

Indeed, in a preferred configuration of this multi-component embodiment,horizontal support bars are adjustable (using, for example, C-channelmembers with a plurality of sizing holes 60) to allow for the width W ofholder 50 to be adjusted, as best shown in FIG. 15. In this particulararrangement, horizontal support bars 56 are formed as horizontalextensions of side support members 52 and 54. In particular, sidesupport member 52 is formed to include horizontal portions 52-A and52-B. Similarly, side support member 54 is formed to include horizontalportions 54-A and 54-B. Horizontal portions 52-A and 52-B are formed as,for example, C-channel elements, that allow for horizontal portions 54-Aand 54-B to slide within the interiors thereof (indicated in phantom inFIG. 8). Horizontal portions 54-A and 54-B are shown as formed toinclude a plurality of sizing holes 60, which align with alignment holes58 in horizontal portions 52-A and 52-B. Once the desired width W ofholder 50 is found, fixing pegs 59 are positioned through holes 58, 60to secure the horizontal width of holder 50. Other arrangements maybeused besides fixing pegs and sizing holes to provide and fix the widthadjustment of holder 50. For example, a clamping mechanism may be used.Moreover, while a pair of horizontal support bars 56-1, 56-2 is shown inFIGS. 14 and 15, it is to be understood that any other suitable numberof horizontal support bars (including a single support bar) may be usedand fall within the scope of this invention.

As best shown in FIGS. 14 and 16, attachment means 18 of multi-componentportable holder 50 comprises a pair of support brackets 66 and 68 thatare used to couple holder 10 to shelf 20 of wall-mounted cabinet 22 (itis to be understood that a pair of bolts as described above mayalternatively be used in this embodiment). Bracket 66 includes an upperbracket piece 65 that fits behind left-hand sidewall 26 of cabinet 22.Bracket 68 similarly includes an upper bracket piece 69 that fits behindright-hand sidewall 26 of cabinet 22. By using bracket pieces 65 and 69to engage sidewalls 26, holder 50 is held fixedly in place with respectto cabinet 22. Front brace members 67 and 70 are also included inbrackets 66, 68 and are positioned against the front face of shelf 20.This arrangement is more than sufficient to securely hold a laptop inplace.

FIG. 16 is an enlarged view of the engagement of support bracket 66 withthe left-hand sidewall 26 of cabinet 22. The positioning of upperbracket piece 65 behind sidewall 26 is clearly evident in this view, asis the positioning of front brace member against the front face of shelf20.

FIGS. 17 and 18 illustrate an alternative adjustable portable holder 80formed in accordance with the present invention. In this embodiment,both the length of support tray 12 and the width of upper endtermination 16 are adjustable. In particular, support tray 12 is shownas being supported by a central adjusting bar 125, with tray 12including a slide rail 127 formed on the underside thereof that engagesadjusting bar 125 to allow for tray 12 to be moved vertically withrespect to upper end termination 16 (as shown by the double-ended arrowin FIGS. 17 and 18). Upper end termination 16 is itself adjustable inwidth, so as to accommodate cabinets of differently sized openings. Inthis case, upper end termination 16 includes an adjustable member 163,with upper bracket pieces 65 and 69 attached to opposing ends thereof.Adjustable member 163 includes telescoping apparatus that allows forbracket pieces 65, 69 to be moved “in” and “out” until both engagecabinet walls. Once engagement is secured, a locking component is usedto hold adjustable member 163 in place.

While the embodiments as described above are particularly well-suitedfor use with a standard-sized laptop computer, as the overall size ofelectronic devices continues to shrink (such as, for example, tablets,e-readers, cell phones, and the like), other embodiments have beendeveloped that provide additional features that may be of particularbenefit for these small devices. In particular, and as will be discussedbelow, these features include (but are not limited to) being able tomodify the viewing angle for a particular device (and also modify theviewing angle for a particular orientation of a device), as well aspivoting the entire holder to a preferred location. These features areprovided without compromising the portability of the holder itself, orcompromising the means used for attaching the holder to a shelf or otherlocation.

Referring now to FIGS. 19-21, a further embodiment of a device holder200 according to this invention is shown mounting a tablet 202 to thebottom panel 204 of a cabinet 206 having a door 207. It should beunderstood that essentially any other electronic device of a size aboutthe same as or smaller than the tablet 202 may be supported by thedevice holder 200, and the device holder 200 may be mounted toessentially any generally horizontally oriented panel in a mannerdiscussed below. As such, the tablet 202 and cabinet 206 are shown inthe Figs. for purposes of illustration only.

As best seen in FIGS. 20 and 21, the device holder 200 comprises a post208 and a mounting bracket 210. The post 208 has an upper end connectedto the mounting bracket 210 as discussed below, and a lower endconnected to a base support 212. For purposes of the present discussion,the term “upper,” “lower,” “top,” “bottom,” “upwardly” and “downwardly”refer to the orientation of the device holder 200 as depicted in theFigs. In the preferred embodiment, the base support 212 has threeupstanding ribs 214, 216 and 218 which are spaced from one anotherforming channels 220 and 221 between them. A third channel 223 is formedbetween the rib 218 and post 208. The length of the base support 212,and the number of ribs 214-218 and channels 220, 221, 223, may be variedas desired. A top support 222 formed with an outwardly extending finger224 is located on the post 208 in between its upper and lower ends. Thetop support 222 includes a cam lock 226 which is movable between alocked position in which the top support is releasably fixed to the post208, and an unlocked position wherein the top support 222 may be movedto any desired position between the upper and lower ends of the post208. As shown in FIG. 19, the bottom end 203 of the tablet 202 may restwithin anyone of the channels 220, 221 or 223 in base support 212 andits top end 205 is retained on the top support 222 by finger 224. Sincethe top support 222 is movable along the post 208, electronic devices ofdifferent heights are readily accommodated by the device holder 200 ofthis invention.

The mounting bracket 210 comprises a top plate 228, a bottom plate 230and a side plate 232 connected substantially perpendicularly to and inbetween the top and bottom plates 228, 230 forming a structure in thegeneral shape of a “C.” A downwardly extending lip 234 is connected toor integrally formed with the bottom plate 230 at substantially a rightangle thereto. The lip 234 is formed with a slot 236 for purposes tobecome apparent below. The mounting bracket 210 further includes aplunger 238 comprising a rod 240 with a head section 242 at its lowerend and a pad 244 mounted to its upper end. The rod 240 extends througha bore 245 in the bottom plate 230 of mounting bracket 210 such that thepad 244 faces and is oriented generally parallel to the top plate 228.

In the presently preferred embodiment, a locking lever 246 is mountedwithin the slot 236 formed in the lip 234 and has a bore 247 thatreceives the rod 240 of plunger 238. See FIG. 23. A coil spring 248extends between the locking lever 246 and the bottom plate 230 ofmounting bracket 210. In the locked position depicted in FIG. 21, thelocking lever 246 is oriented at an angle relative to the bottom plate230 as a result of the spring force exerted by the coil spring 248. Therod 240 engages an edge of the bore 247 in locking lever 246 to retainit, and the plunger 238, in the vertical position shown in FIG. 21wherein a space 250 is provided between the pad 244 and bottom surfaceof top plate 228. In order to vary the height dimension of space 250,and ensure that a horizontal panel of given thickness is firmly engagedbetween the top plate 228 and pad 244, the locking lever 246 may bepivoted upwardly toward the bottom plate 230 of mounting bracket 210 toan unlocked position thus allowing the rod 240 to slide upwardly ordownwardly within the bore 245 in bottom plate 230 and within the bore247 in locking lever 246. Once in the desired position, with the panelsandwiched between the top plate 228 and pad 244, the locking lever 246may be released and the coil spring 248 then returns the locking lever246 to its angled, locked position. As illustrated in FIG. 21, thebottom panel 204 of cabinet 206 may be received within the space 250between the pad 244 and bottom surface of top plate 228. Preferably, thetop plate 228 has a thickness such that the door 207 of cabinet 206 maybe closed when the device holder 200 is mounted thereto.

As shown in FIGS. 21 and 22, the upper end of post 208 mounts an endplate 252 which is oriented at an angle relative to the post 208. Theend plate 252 of post 208 is connected to the bottom plate 230 ofmounting bracket 210 by a bolt 254 and nut 256 which are not tighteneddown but permit relative pivotal movement of the post 208 with respectto the mounting bracket 210. It should be understood, that any otherpivotal connection between the post 208 and mounting bracket 210 may beemployed, and the nut-and-bolt arrangement shown in the Figs. is forpurposes of illustration only. It can be appreciated from FIG. 21 thatwhen the mounting bracket 210 is mounted to a horizontally orientedpanel, the post 208 is angled relative to such panel, which, in turn,disposes the tablet 202 or other electronic device carried by the post208 at the same angle. Additionally, the angle at which the tablet 202is oriented may be varied by placing its bottom edge 203 in a differentchannel 220, 221, or 223. Such angulation of the post 208 helps avoidglare and makes it easier to view and operate the tablet 202.

Referring now to FIGS. 22-24, a still further embodiment of a deviceholder 258 is shown for mounting a tablet 202 or other electronic deviceto the bottom panel 204 of cabinet 206 or other horizontally extendingpanel. The device holder 258 includes a post 260 pivotally mounted to amounting bracket 262 such that the post 260 is oriented at an anglerelative to the mounting bracket 262 as in the embodiment of FIGS.19-21. The mounting bracket 262 is similar to mounting bracket 210described above in connection with a discussion of FIGS. 19-21, exceptit has a top plate 264 segmented into two sections 266, 268, a bottomplate 270 formed with a cut-out area 272 and two downwardly extendinglips 271, 273, and, a side plate 274 connected between the top andbottom plates 264, 270. Instead of a single plunger 238, the deviceholder 258 has two plungers 238 each carried by the bottom plate 270which cooperate with one of the sections 266, 268 of the top plate 264to clamp a horizontal panel between them in the same way as describedabove in connection with a discussion of FIGS. 19-21. As such, the samereference numbers are used to identify elements in FIGS. 22-24 which arecommon to those in FIGS. 19-21 as discussed in detail above.

The main difference between the device holders 200 and 258 is the mannerin which a tablet 202 or other electronic device is carried by theirrespective posts 208, 260 and angled relative to the horizontal panel towhich such device holders 200, 258 are mounted. In the embodiment ofFIGS. 22-24, a base support in the form of an end cap 274 having asingle elongated rib 276 is secured to the lower end of post 260 inposition to receive and support the bottom end 203 of tablet 202 orother electronic device. A carriage 278 having spaced, tapered arms 280,282 is movable to different locations along the post 260. As illustratedin FIG. 24, with the carriage 278 positioned closer to the end cap 274the tablet 202 rests against the tapered arms 280, 282 at a relativelyupright angle compared to when the carriage 278 is moved further awayfrom the end cap 274 and the tablet 202 rests against an outer edge ofeach arm 280, 282.

Although the specification above necessarily includes numerousspecificities, these should be construed as illustrating some of thepossible embodiments and applications of the invention and not aslimiting the scope thereof. For instance, the portable holder of thepresent invention may be formed of a variety of different materials, orany desired combination of materials, including plastics, metals,composites, wood, or the like. And while the holder has been generallyconceived for the purpose of holding a laptop computer, it is equallysuitable to support any type of communication or computing device in anout-of-the-way location, above a countertop and supported along a shelfof a wall-mounted cabinet. Therefore, the scope of the present inventionshould be determined solely by the appended claims and their legalequivalents rather than by the specific above-described embodiments.
